Hi, I was playing with some code and came upon this situation. > x <- c(1, rep(0,9)) > x [1] 1 0 0 0 0 0 0 0 0 0 > idx <- 1:10 > x[idx] <- x[idx] + 1 > x [1] 2 1 1 1 1 1 1 1 1 1
This is expected. But if I do: > x <- c(1, rep(0,9)) > x [1] 1 0 0 0 0 0 0 0 0 0 > idx <- rep(0,10) > idx [1] 0 0 0 0 0 0 0 0 0 0 > x[idx] <- x[idx] +1 > x [1] 1 0 0 0 0 0 0 0 0 0 I was expoecting that when all the elements of idx are set to 0, x[0] would become 11. Could somebody explain why this behavior occurs?
